Estrous synchronization is typically associated with artificial insemination (AI) programs, and is therefore often viewed as impractical or impossible to use within natural-service herds. With 92% of beef herds exclusively implementing a natural-service breeding environment (NAHMS, 2009), estrous synchronization has a place in natural-service breeding systems if implementation can be adapted into normal daily tasks.
Using Estrous Synchronization in Natural-Service Breeding Situations
Calving season has started or will be starting in the near future for most producers. Nutritional management of the cow herd is more important during the periods of late pregnancy and early lactation than any other.
Percent of calf crop weaned on any operation is the single largest factor influencing profitability. Subsequently, herd bulls influence herd fertility more than any other single animal.
The Estrus Synchronization Planner has been available since 1998, developed by Iowa Beef Center. It has evolved over the years, proving to be an effective and easy tool to help select and implement synchronization protocols.
